Good Evening!

Tomorrow we have our deadline for the SED v1-2. So I think it is time to show you our current design and layout. As you might have noticed it changes quite often ;).

In comparison with the previous layout you can see that the battry pack stands for it self and the size of the electronics box has been reduced. For this layout we also use another bulkhead to ease the mounting and reduce the mass.
The layout seen from above.

The electronics box is as mentioned, reduced by size. Inside the box we will have two PCB's for the electronics. These  will be separated using twelwe spacers. The spacers will also be used for the attachment of the PCB's.

The outer structure of the chambers have not been changed since the last pictures, but the  inner structure is more detailed. We have added a small PCB where the temperature and pressure sensor will be placed. 

Power will be conducted to the brown copper plate using cables attached to the four screws at the corners. The  power will be led to the resistance wires which will be attached to the copper plates. The resistance wire will then heat and melt the solder wire wrapped around the resistance wire. 
To prevent a short circuit, a slit will be made below each copper plate .
